Benelux Economic Union (bĕnˈəlŭksˌ) [key], economic treaty among Belgium, the Netherlands, and Luxembourg. It arose out of a customs convention signed in 1944, but was not fully established until 1958. The union was established to promote free movement of workers, capital, goods, and services in the Benelux region. All three countries were also founding members of what has become the European Union (EU), which has implemented these same reforms. Benelux was the first entirely free international labor market, but its goal of merging the fiscal and monetary systems of the three countries was only largely fulfilled when most EU nations replaced their currencies with the euro (2002).
